SPECIFICATION forming part of Letters Patent No. 655,271, dated August '7, 1900.

Application filed December 16, 1899. Serial No. 740,544. (No model.)

To [l/ZZ whom it may concern.-

Be it known that 1, WILLIAM HENRY PFEIF- FER, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Impact-Motors, and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same, ref-.

erence being had to the accompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

The object of my invention is to present a simply-constructed, highly-efficient, durable, and compact form of water-motor in which the full force of an incoming volume of water will without waste be utilized as a propulsive agent.

Generally stated, the invention consists in a motor comprising a sectional casing practically inclosing a double-bucketed turbine wheel, the buckets being arranged on opposite sides of a disk or plate constituting the body of the wheel, the latter being operatively housed between the sections of the casing and the buckets working in alined circumferential grooves of like size formed in the inner opposing faces of the sections. The buckets are preferably semicone-shaped, that portion which would form the half base of the cone constituting the mouth, the apex being by preference rounded, whereby to conform to the water-escape opening located adjacent thereto. The buckets on one side of the disk alternate with those on the OPPO. site side-that is to say, the mouths of the buckets on one side lie in a plane about midway of the length of those on the other sideso that the wheel will receive alternate and at the same time continuous impulses from the stream of water entering the casing from a jet-nozzle, preferably locatedat its top and disposed at-such angle with relation to the buckets as to cause the latter to receive the full charge of the'water. By the arrangeinent of the buckets described it will be seen that the discharge-opening at the apex of a bucket on one side of the disk will come about opposite the center of the bucket on the opposite side thereof, so that the jet of water that enters the bucket on one side of the disk will have to escape from this bucket to the adjacent one on the opposite side of the disk and discharge in a direction directly opposite that in which it initially entered, and vice versa, and in thus escaping impinges against a body of static water confined between the adjacent buckets and against the incoming jet of water.

The invention consists, further, in the novel construction and combination of parts of a motor, as will be hereinafter described and claimed.

In the drawings hereunto annexed and forming apart of this specification, Figure 1 is a view in elevation, partly in section, dis playing the parts of the motor assembled. Fig. 2 is a view in transverse section taken on the linemc, Fig. 1. Fig. 3 isafragmentary detail view in section showing the arrangement of the buckets with relation to each other.

Referring to the drawings, A designates the casing of the motor, the same being constructed, preferably, of cast metal and in two sectionsa a held together by bolts a, passed through ears a provided for the purpose. Each half of the casing is formed on its inner face with a semicircular circumferential groove (t the two grooves mating and forming a chamber in which work the buckets B. The buckets are carried on opposite sides of a disk 6, space being left between the opposing faces of the sections to permit it freely to rotate, the disk being cast integral with or secured to a hub which also works in a chamber formed in the two opposing faces of the sections. The disk is keyed or otherwise fixed to ashaft b workingin bearings formed in the sections, the shaft being connected by a belt and pulley connection (not shown) with any object to be driven. The casing is provided with a base I) to permit attachment to a suitable support and with a dischargemouth N, as clearly shown in Fig. 1.

As before stated, the buckets B are hollow semicone-shaped structures attached in any preferred manner to opposite sides of the disk, with the apex of the buckets on one side of the disk terminating at about midway of the length of those onthe opposite side thereof, and at the apex of each bucket is a dischargeopening b, through which the water con- ICO tained in a bucket on one side of the disk is discharged into the corresponding bucket on the opposite side thereof, and vice versa, and thence escapes in the manner described.

The water is supplied to the buckets through a jet-nozzle 0, having a threaded connection, as at c, with the two sections of the casing and provided at its inlet end with coupling by which to effect connection with the source of Patent, is

1. In a motor, the combination of a casing provided with a supply and discharge, a revoluble disk housed within the casing, and buckets carried on opposite sides of the disk, the buckets on one side of the disk discharging into those on the opposite side thereof, and at about midway of their length, and vice versa, substantially as specified.

2. A motor comprising a sectional casing partially inclosing a double-bucketed turbine wheel, the buckets being arranged on opposite sides of a disk or plate, constituting the body of the wheel, the buckets on one side of the disk discharging into those on the opposite side thereof, and at about midway of their length, and vice versa, the disk being housed between the sections of the casing, and the buckets working in alined circumferential grooves of like size, formed in the inner opposing faces of the sections, substantially as specified.

3. A motor comprising a sectional casing partially inclosing a double-bucketed turbine wheel, the buckets being semicone-shaped, and arranged on opposite sides of a disk or plate constituting the body of the wheel, and those on one side of the disk discharging into those on the opposite side, the disk being housed between the sections of the casing, and the buckets working in alined circumferential grooves, of like size, formed in the inner opposing faces of the sections, and a jet-' nozzle discharging into the casing, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
